RAILWAY SlGNAL-REPEATER.

Specification of Letters Patent.

Patented Dec. 19, 1905.

Application filed July I5, 1905. Serial No. 269,801.

To aZl whom, it may concern:

Be it known that we, FREDERICK B. WIE- GAND and WILLIAM V. MoAK, residents of the city of Utica, county of Oneida, and FRANCIS B.HARRINeToN,a resident of Men-ands,Alban y county,N ewYork. citizens of the United States ofAmerica. have invented certain new and useful Improvements in Railway Signal-Repeaters, of which the following is a specification.

Our invention relates to repeaters for railway signal-stations; and the object of our invention is to provide a repeating-sign al device which may be placed in the various block-signal stations for the purpose of indicating the position of the signal on the track, so that it will duplicate the track-signal, and being in the house of the operator will at a glance inform him of the position which the signal occupies on the road. We attain this object by means of the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a front elevation with the front casing removed. Fig. 2 is a side elevation with the casing removed. Fig. 3 is a plan of the bottom of the repeater. Fig. 4 is afront elevation.

Similar letters refer to similar parts throughout the several views. I

Mounted on a suitable block A we place the magnets B B O C, respectively, which are connected by wires to a primary supply. (Not shown.) We mount the bell-crank levers D and .E between the magnets B and O by means of the bolts F and G, respectively, to the projections ff on the block A, (see Fig. 3,) the armatures (Z and 6 being attached to the short arms of the bell-crank levers D and E, respectively. For the purpose of regulating the position of the armatures d and c in reference to the magnets we place the regulating-screws J and K, secured to the brackets L and L, respectively, which brackets are secured to the back plate V in such a position that they will bear against the long arms of the bell-crank levers D and E, respectively, and limit the movement of said arms. I

Mounted in bracket N and passing through the plate M is a rod O, which carries on its end a signal-arm P. It also preferably carries a weight R, tending to restore the arm to its normal position when contacts are withdrawn. Said rod also carries a contact-plate S, which is located between the levers D and E, at the ends thereof preferably, and in such position that the lateral movement of the levers D and E will cause a rotary movement of the contact-plate S,and therefore the signal-armP.

The normal position of the signal-arm when it is unaffected by the operation of the magnets is that shown in Fig. 4, Where it is between the horizontal and the nearest that it can approach the vertical. When the magnets B B are energized, the armatures connected with the levers D will cause the said lever to engage the contact-arm S and move the same to the right, which will raise the signalarm P to a horizontal position. WVhen the magnets (.l are energized, the armature 6 will be attracted and the lever E will act upon the contact-plate S and cause the signal-arm to assume an angle of about sixty degrees, showing the way clear. Each of the signals-on the road are connected electrically with a repeater in the signal-house inv such a manner that when the signal on the road is placed at danger the signal-arm being horizontal the magnets B B of the repeater will be charged and the lever D caused to operate on the contact-plate S, which will move the signal-arm P to a horizontal position corresponding to that of the signal on the road. In the same way the signal on the road when it is in a clear position will electrically charge the magnets O O and cause the lever E to act upon the contactplate S and throw the signal-arm P to the clear position corresponding with that of the signal on the roadto which it is connected.

We have not shown the electrical connections between the signal on the road and the signal-repeater described, as it is immaterial how such connections are made.

What we claim as our invention, and desire to secure by Letters Patent, is-

.In a railway signal-repeater, the combination of two or more magnets; a contact-plate; signal-arm; a rod carrying said contact-plate and signal-arm; a means for moving said contact-plate and therefore said signal-arm to indicate either of two positions, determined upon the action of said magnets; a third position of said signal-arm being indicated when said magnets are not energized.
